You are using requested_level as a variable passed from the Alexa command? If so I’m not sure you can do that, I didn’t find anything about that when i was looking for it.
Yes, this is what I’m trying. I’ve not specified anything else on the routine action other than the text. I was expected to parse somehow what is after the text and send it as a variable, but I was wrong. It is not mapping the correct text, sometimes is taking a different routine (tv volume up, instead of tv volume) and says that the routine doesn’t support that … Not sure if is possible, that’s why I’m asking
